' rea ers Specification of Letters Patent. Patented Oct, 10, 1916 Application filed February a, 914. Serial No. 817,547.

To all whom it may concern;

Be it knownthat I, EARL P. HONN, a citiing at Grand Rapids, and State of Michigan, have invented certain new and useful Improvements in Heating Devices; and I do hereby declare the followingto bea 'full,clear, and exact description of the invention, such'a s will enable others skilled in the art to which it' apperytains to make and use the same." i

This invention, relates to improvements in heating devices and more particularly to heaters having vapor burnersfon kerosene or like hydrocarbon fuel, and its object is r to provide a heater whichwill be simple and cheap in construction, cal in operation; to provide an automatic hereinafter'more fully, described, I and parback through said passage into the room.

I comprises a central cup 4 surrounded by a ring 5, both of which are preferably cast integral with the-base and the fuel is admitted to the bottom of the said cup through the pipe 6. A check valve 7 of any suitable form, is preferably located at the endof'the said pipe to prevent soot, etc., dropping therein and obstructing the passage. The air inlet to the burner is through a bifurcated passage 8, preferably formed on the under side of the base 3 and leading to diametrically oppositeisides of the same, where it com ring 5. The air enters the passage 8, pref erablythrough an elbow 12 which has a fine wire, gauze screen 13 which acts as a fire stop and prevents fire from the-burnerescaping above the burner, and it engages the rear An 'inv e rted conical deflector 14: is located within the body 1 with its apex directly.

which the hot products of combustion'pass before entering the chimney through the heat is radiated into the rooms;

The body 1 is provided in itsfront with a t removable door 18 which closes an opening if in the body and is retained therein by a bolt 19 attached to a bar 20, which extends across the opening on. the inside of the body,- said bolt being provided with a wing nut-21 having a conical base which seats in a correby forming an air tight joint.

spondingly tapered recess inthe door, there-f The thermos't tic fuel controller comprises?" a valve of the so called needle type, having an inletv 23, a fuel" supply pipe 24 and an outlet .25 .commun1cat1ng with a fuel ipe-e3 preferably through a sight feed device 26.

The needle 27 of the said valve has a stem which extends upward through a tubular support 28,'the upper end; of which is pref erablylhigher than the fuel level and the upper end of the said stem projects from the tube and is attached to a thermostatic disk 29 located within a ring bracket 30 on the upper end of the tube 28. The disk 29 is of the type which expands when heated and is supported within the bracket by an adjustable screw 31 threaded through a bushing 32, said bushing also being threaded into the bracket and adjustable therein being provided with a lever 33 for that purpose. A stop 34 on the bracket 30 limits the movement of the handle 33 and the screw 31 is provided with a lock nut 35 whereby the adjustment of said screw in the bushing 32 may be maintained and the valve stem27 is threaded at its upper end and provided with limiting nuts 36 adjustable thereon, where-' by the closing movement of the valve may be stopped at a predetermined position. The operation of this device is asfollows: -Assuming the room in which the heater is located to be cold, the thermostatic wafer'29 willbe contracted to its thinnest condition thereby raising the valve 22 from its seat and permitting the fuel free passage therethrough into the cup 4. The fuel is allowed to fill this cup and overflow into the space within the ring 5 and is then lighted through the opening closed by the door 18.

The fuel will burn from within the ring 5,

. combustion is drawn through the bifurcated passage 8 and flows through the orifice 11, supplying oxygen to the flame. The hot walls of the passage heat the air as it passes therethrough, which aids in the vaporization of the fuel. The hot products of combusition rise and are directed by the deflector 14 to the front of the body and thence back to the outlet 15, thoroughly heating the sides and top of the body. Whatever heat remains in the said products is absorbed by the pipe 16 and radiated into the room by the same and the ribs thereon. As the temperature in the room rises the wafer 29 will expand, forcing the needle valve toward its seat and restricting the fiow of the fuel, and when the desired temperature has been attained the valve will be sufficiently closed to permit the passage of only enough fuel to keep the flame in the burner, only suflicient to maintain the temperature constant. In this position the limiting nut 36 will engage the I bracket 30, preventing the valve from further closing should the temperature of the room rise due to external influence, thereby insuring a continuous flame at the burner.

The degree of temperature to be maintained in the room may be regulated by vmeans of the adjusting screw 31,-,by which the disk 29 may be raised or lowered, necessitating more or less expansion to close the valve 22.

It is often desirable to raise the temperature in the room for short periods, and to enable this to be done without interfering with the normal adjustment of the regulator the bushing 32 may be turned by means of the lever 33, which will raise the disk and needle valve, permitting more fuel to pass to the burner, and when'it is desired to again reduce the temperature to the normal degree the bushing may be rotated to its former position by turning the lever 33 back against the stop 34. g 4

A heater comprising a main chamber having a base, said base having a central aperture therein, a flange extending upwardly from said base and constituting an elongated chamber, a cover for said chamber providedwith a central aperture, a collar surrounding the aperture and the base and cover, a second flange formed integral with the base intermediate the outer flange and the collar and terminating short of said cover, the said collar and the second flange extending through the aperture in the said 7 forming a burner, and means for supplying fuel through the aperture in the base to the burner.
